AUGUST KIND, OF BERLIN, GERMANY, ASSIGNOR TO HEINRICH MESTERN, OF SAMEPLACE.

VENTI LATOR.

SPECIFICATION forming part of Letters Patent No. 246,149, dated August23, 1881.

Application filed February 25, 1881.

To all whom it may concern:

Be it known that I, AUGUST KIND, of Berlin, in the Kingdom of Prussia,German Empire, have invented a new and useful Improvement in HydraulicVentilators for Buildings and Dwelling-R001ns, of which the following isa full and clear description, reference being had to the accompanyingdrawings, which make part of this specification, and in which the sameletters indicate corresponding parts in all figures.

The hydraulic ventilator or the air-propelling apparatus is worked bymeans of water under pressure; and its object is to refresh, to

Is purify, to moisten, and to cool (respectively to heat) the air ofdwelling and other rooms, theaters, buildings, churches, &c.

The accompanying drawings form a part of this specification andillustrate the invention.

' Figure 1 is a vertical section of the apparatus. Fig. 2 is ahorizontalsection of the same, taken through the passages F. Fig. 3 is a View ofthe apparatus applied, showing the feeding and discharge pipes and someof the circumjacent parts of a room.

Similar letters of reference indicate corresponding parts in all thefigures.

The cylinder 0, open on the lower, end, is fastened concentrically onand into the larger 0 cylinder A, the bottom of which is slightlyhollowed out. The annular space E, between the two cylinders A and 0,forms the air-passage which leads to the air-distributer K on top of theapparatus, through the perforated cover D of which the air passes intothe room or into a draft-pipe, leading off the bad gasesofdwelling-rooms, the vapors of kitchens, 81c, into the open air or intoa chimney. The inner space ofthe cylinderOforms the spray-chamber, com-0 municating on the lower end with the air-passage E, on the upper endwith the air-openings F under the bottom of the distributer K. To theunder side of this bottom is fastened the spraynozzle H, of common or ofpeculiar 5 construction, receiving the water which is under pressurefrom the conducting-pipe P, and discharging it in form of a divergingcone (N0 model.)

against the inner walls of the cylinder 0. By the force of the water thelatter is partly deflected from the walls of the cylinder 0 against theopposite walls, from where it drops down to the bottom B of the cylinderA; partly it falls down directly to the bottom 13, and is carried off bythe waste-pipe Q, furnished with a trap, M.

The working of the apparatus is as follows: The water ejected andspurtin g from the nozzle H with great force fills the cylinder 0 with avery fine divided spray of water, which acts in downward direction likea continuous plun- 6c. ger, carrying along all the air contained in thecylinder 0, and sucking, therefore, new air, gases, or vapors throughthe openings F. When this mixture of air and water spray has reached thelower part of A the purified and cooled (orin winter-time, when thewater is used hot, heated) air separates from the water, is pressedupward, and escapes through the openings on top of the distributer K.

The passages F are in effect holescut into the cylinders A and O, whichholes are closed on all sides between the cylinders. The airpassages Econtinue to the dome K, except where they are interrupted by thepassages F.

It is easy to understand that when the air of a room is drawn into theopenings F, and after passing the apparatus is forced again into theroom, it is purified and cooled, (or heated,) and that in this manner avery healthy and refreshing ventilation is produced. Instead of drawingthe air from the room it may be fed to the apparatus from outside of theroom by a pipe leading to the openings F, as shown in Fig. 1 by dottedlines.

In Fig. 3 is shown,in smaller scale, the apparatus as used in a kitchento free the latter from moisture and moist vapors.

Z is the sink, into which the waste water of the pipe Q is carried off.

Y is a pipe leading the drawn-oft vapors and 0 air into the chimney.

I propose to make a separate application for patent for the nozzleshown.

After so having described clearly and fully my invention, Iwant tosecure by Letters Pat- This specification signed by me this 11th day entof December, 1880.
